Phosphates are particularly important for the growth and development of plant roots, and hence are one of the most common fertilizers used in agriculture.

Phosphates are also utilized in detergents and are needed, in small quantities, for heating systems. However, high concentrations of phosphates can cause environmental pollution as they are a primary cause of eutrophication.

For these reasons, it is necessary to closely monitor the phosphate levels present in both municipal and industrial waste water.

The HI 96717 measures the phosphate (PO43–) content in water samples in the 0.0 to 30.0 mg/L (ppm) range.

Order Information:HI 96717 are supplied with sample cuvettes with caps (2), 9V battery and instruction manual.
